Cameras capture illegally parked cops

Jimmy Justice -- he keeps his real name a secret for obvious reasons -- stalks New York streets looking for official parking cheaters to film. Finding them never takes long. "Justice" talked to MSNBC.com as long as we promised not to reveal his identity.

"Writing summonses is not about public safety; it's about revenue," says the vigilante. "These people are tax collectors. It makes the whole system into a big joke when they violate laws."

If you've ever seen a cop break the law with seeming impunity, you'll cheer Jimmy Justice when you find his video clips on YouTube. The confrontations are irresistible. ("I'm good at pushing other people's buttons," the 36-year-old budding filmmaker says.)
